In Ruby, the **`chomp` method** removes the #key# record separator: a character that indicates the end of one record and beginning of the next record #key# from the end of the string and returns the string. 
> A **record** in the computer is a collection of data items arranged for processing.
  
This is shown in the illustration below:

# Syntax
The `chomp` method is declared as follows:
```
str.chomp
```
OR
```
str.chomp(substring)
```

# Parameters
The `chomp` method either takes no arguments or just one argument. In the case of an argument, a `substring` is specified to be removed from the string. 

# Return value
The `chomp` method returns the string with no record separator at the end of the string. 

* If #key# $/: pre-defined variable used as the input record separator and has a default value of "\n" #key# has not been changed, the `chomp` method will remove the carriage return characters from the string. These include `\n`, `\r` and `\r\n`. 

* The `chomp` method removes trailing newlines `(\n)` from a given string if $/ is empty. 

# Examples
The examples below show the use of the `chomp` method in Ruby:

#Example 1
puts "bye\n".chomp

#Example 2
puts "bye\r\n".chomp

#Example 3
puts "bye".chomp('e')
